So a couple of weeks ago I got a faint positive pregnancy test, I had a doctor's appointment last Wednesday they said their test was faint as well and they did an ultrasound. They said I'm possibly pregnant with twins...TWINS!!! they checked my betas and also again Friday morning, I go back to the doctor tomorrow for a repeat ultrasound to make sure they are growing. This cycle I had an hsg and also took opks. They were expecting me to be around 7 weeks, but when they measured the sacs it was only around 4 weeks, but this cycle I didn't not ovulate until 2 and a half weeks after my period, could this have something to do with them measuring smaller? I'm worried it could be a chemical pregnancy. anyone ever experience this or have any thoughts concerning this?
